Complete Bambu Lab P1S Settings Guide: PLA, PETG, ABS, TPU

The Bambu Lab P1S is one of the best enclosed 3D printers on the market. With its CoreXY design, direct-drive extruder, and all-metal hotend, it can handle everything from basic PLA to engineering-grade materials like ABS and PA (nylon). But even a great printer needs the right settings for each material.

This guide provides tested slicer profiles for PLA, PETG, ABS, TPU, and several specialty filaments on the P1S. All settings are for BambuStudio or OrcaSlicer (which shares the same profile format) with the stock 0.4mm nozzle.

General P1S Capabilities

Before diving into material-specific settings, here is what makes the P1S capable:

• Max nozzle temperature: 300°C (all-metal hotend)
• Max bed temperature: 110°C
• Enclosed chamber: Yes (important for ABS, ASA, PA)
• Max recommended speed: 300 mm/s (with input shaper active)
• Max volumetric flow: ~24 mm³/s (stock hotend)
• Direct-drive extruder: Short retraction distances
• Auto-leveling: LiDAR-based mesh leveling
• AMS compatible: Yes (automatic filament changes)

PLA Settings

PLA is the easiest material to print on the P1S. The enclosed chamber is unnecessary (and can even cause heat creep with PLA), so keep the door open or remove the front panel for PLA printing.

Nozzle Temperature: 210-220°C
Bed Temperature: 55-60°C
Print Speed: 200-300 mm/s (the P1S handles PLA at speed)
Outer Wall Speed: 150-200 mm/s
Travel Speed: 350 mm/s
Acceleration: 5000-10000 mm/s²
Retraction Distance: 0.8 mm
Retraction Speed: 30 mm/s
Cooling Fan: 100% after first layer
First Layer Speed: 50 mm/s
First Layer Temperature: 220°C (slightly hotter for adhesion)
Infill Pattern: Gyroid (for general use) or Grid (for strength)
Infill: 15-20% (decorative), 40%+ (functional)
Layer Height: 0.2mm (standard), 0.12mm (detail), 0.28mm (fast draft)

Tips for PLA on P1S:

• Open the front door or remove the top lid. PLA can experience heat creep in the enclosed chamber.
• The stock BambuStudio PLA profile is well-tuned — start there and adjust if needed.
• For Bambu Lab's own PLA, the RFID spool sets all temperatures automatically.

According to Bambu Lab's filament guide, their PLA filament is specifically formulated for high-speed printing on their machines.

PETG Settings

PETG prints well on the P1S but requires a few adjustments compared to PLA. The enclosed chamber can stay closed for PETG — it benefits from a slightly warmer environment.

Nozzle Temperature: 235-245°C
Bed Temperature: 70-80°C
Print Speed: 150-200 mm/s
Outer Wall Speed: 100-150 mm/s
Travel Speed: 300 mm/s
Acceleration: 5000-7000 mm/s²
Retraction Distance: 0.8-1.0 mm
Retraction Speed: 25 mm/s (slower than PLA)
Cooling Fan: 40-60% (never 100%)
First Layer Speed: 40 mm/s
First Layer Temperature: 240°C
Z Hop: 0.2 mm (reduces stringing)
Infill Pattern: Gyroid or Grid
Layer Height: 0.2mm (standard)

Tips for PETG on P1S:

• Apply glue stick to the PEI bed. PETG bonds too aggressively to bare PEI and can rip chunks off the build plate. A thin layer of glue stick acts as a release agent.
• Reduce fan speed — PETG needs some cooling but too much causes layer adhesion problems.
• If you get stringing, reduce temperature by 5°C before increasing retraction. As Prusa's PETG guide notes, temperature is the biggest factor in PETG stringing.

ABS Settings

ABS is where the P1S's enclosed chamber truly shines. The enclosure maintains a stable ambient temperature that prevents warping and cracking.

Nozzle Temperature: 245-255°C
Bed Temperature: 100-110°C
Print Speed: 150-200 mm/s
Outer Wall Speed: 100-150 mm/s
Travel Speed: 300 mm/s
Acceleration: 5000-7000 mm/s²
Retraction Distance: 0.5-0.8 mm
Retraction Speed: 30 mm/s
Cooling Fan: 0-20% (minimal cooling for ABS)
Chamber Temperature: Target 45-55°C (achieved by the heated bed in the enclosure)
First Layer Speed: 40 mm/s
First Layer Temperature: 255°C
Infill Pattern: Gyroid
Layer Height: 0.2mm (standard)

Tips for ABS on P1S:

• Keep the enclosure fully closed. ABS needs a warm, stable chamber to avoid warping and cracking.
• Let the chamber pre-heat for 10-15 minutes before starting. Print a skirt with several loops to warm things up.
• ABS produces fumes — the P1S has an activated carbon filter, but print in a ventilated area regardless.
• The Bambu Lab ABS filament is specifically tuned for their printers and prints reliably.

According to 3D Printing Industry's P1S review, the P1S's enclosure makes ABS printing accessible to users who previously struggled with it on open-frame printers.

TPU (Flexible) Settings

The P1S's direct-drive extruder handles TPU well, though you need to slow down significantly compared to rigid materials.

Nozzle Temperature: 220-235°C
Bed Temperature: 50-60°C
Print Speed: 30-50 mm/s (TPU cannot handle high speed)
Outer Wall Speed: 25-40 mm/s
Travel Speed: 100-150 mm/s (slower to prevent pulling on the flexible filament)
Acceleration: 1000-2000 mm/s² (low to prevent filament buckling)
Retraction Distance: 0.2-0.5 mm (minimal — TPU compresses)
Retraction Speed: 15-20 mm/s (slow)
Cooling Fan: 50-80%
First Layer Speed: 20-30 mm/s
Infill Pattern: Gyroid (provides flexibility)
Layer Height: 0.2mm

Tips for TPU on P1S:

• Disable the AMS for TPU. Flexible filament does not feed reliably through the AMS tubes. Load TPU directly into the extruder using the external spool holder.
• Keep retraction minimal. TPU compresses in the feed path, and long retraction causes jams.
• For softer TPU (shore 85A and below), reduce speed further to 20-30 mm/s.
• The Overture TPU filament at 95A hardness is a good starting point that is easier to print than softer variants.

ASA Settings

ASA is ABS's UV-resistant cousin, ideal for outdoor parts. Settings are very similar to ABS.

Nozzle Temperature: 245-260°C
Bed Temperature: 100-110°C
Print Speed: 150-200 mm/s
Cooling Fan: 0-20%
Retraction Distance: 0.5-0.8 mm
Chamber: Fully enclosed

ASA smells worse than ABS during printing — definitely use ventilation. The enclosure's carbon filter helps but is not sufficient for extended printing sessions.

PA (Nylon) Settings

Nylon is hygroscopic and demanding, but the P1S handles it with its 300°C hotend and enclosed chamber.

Nozzle Temperature: 260-280°C
Bed Temperature: 85-100°C
Print Speed: 80-120 mm/s
Cooling Fan: 0-30%
Retraction Distance: 0.5-1.0 mm
Chamber: Fully enclosed, pre-heated

Critical: Nylon must be dried before printing. Use a filament dryer like the SUNLU FilaDryer S2 at 70-80°C for 6+ hours before loading. Print directly from the dryer if possible.

According to Polymaker's PA guide, even a few hours of ambient exposure can absorb enough moisture to ruin print quality.

PC (Polycarbonate) Settings

The P1S can print PC thanks to its high-temperature capabilities.

Nozzle Temperature: 270-290°C
Bed Temperature: 100-110°C
Print Speed: 60-100 mm/s
Cooling Fan: 0-10%
Retraction Distance: 0.5-0.8 mm
Chamber: Fully enclosed, pre-heated to maximum

PC requires the hottest settings and the most stable chamber temperature. It warps aggressively without an enclosure.

First Layer Calibration

The P1S has excellent automatic first-layer calibration via its LiDAR sensor, but you can fine-tune:

1. Start a calibration print from BambuStudio
2. Watch the first layer go down
3. Use the micro-adjust feature (0.01mm increments) if lines are too squished or too separated
4. Save the offset for that specific build plate

Speed Tuning

The P1S can theoretically print at 500 mm/s, but quality degrades above 250-300 mm/s for most materials. Here is a practical speed guide:

| Priority | Speed Range | Use Case | |---|---|---| | Maximum quality | 80-150 mm/s | Miniatures, display models | | Balanced | 150-250 mm/s | Functional parts, general printing | | Maximum speed | 250-300 mm/s | Draft prints, iteration prototyping |

Profile Management in BambuStudio

BambuStudio ships with pre-configured profiles for Bambu Lab filaments. For third-party filaments:

1. Start with the closest Bambu Lab profile (e.g., use "Bambu PLA" profile for any PLA)
2. Adjust temperature based on the third-party filament's datasheet
3. Save as a custom profile with the filament name
4. The OrcaSlicer calibration tools can automate flow rate and pressure advance calibration

Final Thoughts

The P1S is remarkably versatile. Its enclosed design, all-metal hotend, and direct-drive extruder mean it can print nearly any filament with the right settings. Start with BambuStudio's built-in profiles, use this guide for third-party filaments, and do not be afraid to push the speed — the P1S's input shaper and mechanical rigidity can handle it. The biggest adjustment most users need to make is remembering to open the door for PLA and close it for everything else.
